<p id="GUID-BEF5EB0F-788A-4412-83C7-7CB31ADB623F">The Oblique Viewer widget displays images in a native coordinate system using an image coordinate system. Oblique images are displayed in a native ICS  to avoid distortion caused by projecting them to a geographic coordinate system or projected coordinate system. The widget allows the user to pan around in the oblique mode, in a single viewing angle, or switch angles to view an area of interest from different angles.</p><div class="section1" id="GUID-4F252793-E555-41C3-A49F-6B69867792FC" purpose="section1"><h2>
